Case Study: Major Healthcare Insurance Company achieves 10-second SLA responsiveness across 125 TB of SQL Server claims data with Quest's Spotlight on SQL Server Enterprise

SQL Server monitoring on 125 TB of healthcare claims data

A major U.S. healthcare insurer that manages claims and eligibility for more than a million subscribers needed continuous, reliable monitoring across a sprawling SQL Server estate — roughly 125 TB spanning three production instances and 28 test environments — to meet a strict 10-second SLA for provider eligibility inquiries routed through BizTalk. The DBA team required 24/7 visibility and fast root-cause analysis to prevent downtime or costly SLA breaches.

They deployed Spotlight on SQL Server Enterprise, using federation for resilient cross-site monitoring, customizable alerts for rapid response, and a playback database to rewind and diagnose incidents. The solution delivered continuous monitoring even during network outages, supported nearly a decade of operations growth to 125 TB, enabled faster troubleshooting and root-cause analysis, and ensured compliance with the 10-second SLA.
